1. What is the scientific name for the kneecap?

• A. Patella
• B. Femur
• C. Tibia
• D. Fibula

Correct answer: A

Rationale: The patella, commonly known as the kneecap, is a small, flat, triangular bone that sits at the front of the knee joint. It protects the joint from impact and helps to transmit force from the quadriceps muscle to the tibia (shinbone).

2. What is the neurotransmitter involved in muscle movement?

• A. Dopamine
• B. Acetylcholine
• C. Serotonin
• D. GABA

Correct answer: B

Rationale: The correct answer is B: Acetylcholine. Acetylcholine is the neurotransmitter involved in muscle movement. It is released by motor neurons at the neuromuscular junction to stimulate muscle contraction. Dopamine is involved in reward and pleasure pathways in the brain, serotonin plays a role in mood regulation, and GABA is an inhibitory neurotransmitter that helps to reduce neural activity. Understanding the specific roles of neurotransmitters is crucial in grasping their functions in the nervous system.

3. Which gland located in the neck is responsible for regulating metabolism, growth, and development?

• A. Parathyroid gland
• B. Thyroid gland
• C. Pituitary gland
• D. Thymus gland

Correct answer: B

Rationale: The correct answer is B: Thyroid gland. The thyroid gland is located in the neck and plays a crucial role in regulating metabolism, growth, and development. It produces hormones such as thyroxine (T4) and triiodothyronine (T3) that control the body's metabolic rate, affecting energy levels and growth. The parathyroid gland (A) regulates calcium levels in the body, the pituitary gland (C) controls several other glands and their hormone production, and the thymus gland (D) is involved in the immune system's development. Therefore, the thyroid gland is the most appropriate choice for the functions described in the question.

4. Which of the following is an example of a decomposition reaction?

• A. 2H2 + O2 → 2H2O
• B. CaCO3 → CaO + CO2
• C. 2Na + Cl2 → 2NaCl
• D. N2 + 3H2 → 2NH3

Correct answer: b

Rationale: Decomposition reactions involve the breakdown of a compound into simpler substances.

5. Identify the participial phrase in the following sentence: "Running through the park, she spotted a squirrel."

• A. Running
• B. through the park
• C. she spotted
• D. a squirrel

Correct answer: B

Rationale: A participial phrase acts as an adjective but is formed from a verb.

6. What is the SI unit of measurement for acceleration?

• A. Meters per second (m/s)
• B. Newton (N)
• C. Meters (m)
• D. Meters per second squared (m/s²)

Correct answer: d

Rationale: Acceleration is measured in meters per second squared (m/s²) in the SI unit system.
